The Red Devil has started the season in scintillating form. Eight goals in four games is an extraordinary return, which could probably be only matched by Cristiano Ronaldo and Lionel Messi. But the England star does have a tendency to score lots of goals in patches which are then followed by lean spells. Injury could also hamper his chances.
